On an exact analytical solution of the Boussinesq equation

A useful exact analytical solution of the Boussinesq equation is discussed and is the most general solution presently available, and in particular yie lds a solution for a finite aquifer. It provides insight into the physical processes arising during the exchange of water between an aquifer and a fre e body of water of varying height as an application and extension of Barenb latt's solution. We also illustrate the value of such a solution to check n umerical and approximate schemes.
